DOJ approves Google's $400 million Admeld purchase

In June, Google acquired the large advertising optimization platform for publishers, AdMeld, for $400 million in cash.

The company launched in 2007 with $30 million in venture capital.

In July, the U.S. DOJ requested more info from Google over its acquisition, for anti-trust purposes.

Today, the DOJ has approved the acquisition:

We're pleased that the U.S. Department of Justice has today cleared this deal. We'll close the acquisition in the coming days and then start the real work-building improved products and services that help our publisher partners to make more informed decisions across all their ad space, and to grow their revenues.

The move is the third major acquisition for Google in the online ad space, with the search giant paying $3.1 billion for DoubleClick in 2007 and $750 million for AdMob in 2009.
